To find the shape of the instrument on the rock door in "The Legend of Zelda: The Wind Waker," you'll need to look for the musical notes engraved on the door itself. Pay attention to the sequence and shapes of the notes, as they correspond to the specific instrument you need to play. You can also consult the game's guide or in-game hints for additional clues. Once you have the shape, use your Wind Waker to play the correct song to unlock the door.
